Schematic Diy Subwoofer Amplifier. 12au7 ecc82 cathode follower tube preamplifier schematic. In this project we are going to design a subwoofer amplifier circuit using ic tda2030 with few cheap components.
The cut off frequency was assumed to be 200hz and the quality factor is assumed to be 0 707. And pass labs are available to personally help you with any questions or concerns. Posting restore restore this posting.
This tda2030 amplifier can produce 14watt output and this can be increased upto 30watt by using another tda2030.
